1. Adrian has a rectangular block with the dimensions 3.5 in by 8.0 in by 5.5
miskamm [114]

Answer:

The density of the block is 2.827 grams/ cubic inch

Explanation:

The density of the block can be obtained by dividing the given mass of the block by its volume.

Density = mass / volume

The mass of the block given is 435.5 grams

The volume of the block can be obtained by using the formula:

Volume = Length X breadth X height

Volume = 3.5 X 8 X 5.5 = 154 in^3

There fore the density will be 435.5 / 154 = 2.827 grams/ cubic inch
